Small Excavators Hydraulic System
Abstract:This paper mainly on small sized excavator hydraulic system design is discussed in this paper.In the thesis, mainly introduced the boom, dipper, bucket hydraulic motion related hydraulic principle is introduced, including the hydraulic cylinder and the hydraulic valve design.It is mainly small excavator hydraulic system oil movement analysis and various hydraulic valve control principles for the design, calculation and further identified the need for complete selection of hydraulic components.Using CAD software to draw a diagram of hydraulic system, hydraulic cylinder part drawing and assembly drawing of small excavator overall.The results show the feasibility of this design.
